Ukuzivocavoca njalo kuthiwa kuyisihluthulelo sokuphila impilo ende nenempilo. Kodwa zimbalwa izifundo eziye zafinyelela ekuqhathaniseni ukuphila isikhathi eside phakathi kwalabo abenza umsebenzi wokuzivivinya ngamandla kanye nalabo abaphila ngokuyinhloko bengawuvivinyi umzimba ngenxa yomsebenzi wabo wokuphila konke.
Manje, uNaoyuki Hayashi noKazuhiro Kezuka abavela eTokyo Tech's Institute of Liberal Arts benze Ucwaningo okungajwayelekile okubekela inselele umbono wokuthi ukuvivinya umzimba ngamandla kwansuku zonke kuhlotshaniswa kahle nokuphila isikhathi eside.
Baqhathanise ubude bempilo yamaqembu amane amaciko obuciko bendabuko base-Japan ngokuhlola idatha evela enanini lamaciko wesilisa aphilayo nashonile angama-699 amarekhodi awo okuzalwa nokufa atholakala esidlangalaleni. Bacabanga ukuthi abalingisi be-kabuki bazophila isikhathi eside ngenxa yezinga eliphezulu lokuzivocavoca umzimba elihilelekile ekusebenzeni kwabo kwesiteji, uma kuqhathaniswa nabasebenzi baseSado, i-Rakugo ne-Nagauta, abaziwa ngokwenza imikhosi yetiye, ukuxoxa izindaba ezihlekisayo nokudlala izinsimbi zomculo ngenkathi behlezi, ngokulandelana.
Ukuzivivinya kanzima akusho ukuthi kunwebe ukuphila
Ngokuhlaziya idatha yokuphila isikhathi eside evela kumaciko omdabu wase-Japan angochwepheshe, abacwaningi e-Tokyo Institute of Technology (Tokyo Tech) bathole ukuthi abalingisi be-kabuki, abaziwa ngokunyakaza kwabo okunamandla, babephila isikhathi esifushane ngokumangalisayo uma kuqhathaniswa namanye amaciko omdabu. Imiphumela iphakamisa ukuthi ukuvivinya umzimba kanzima okuhlobene nomsebenzi kukho konke ukuphila akusho ukuthi kunwebe isikhathi eside.
Ukusebenzisa indlela ebizwa ngokuthi Ukuhlaziywa kwe-Kaplan-Meier, ithole ukuthi, ngokuphambene nalokho obekulindelekile, isikhathi sokuphila sabadlali be-kabuki besifushane kunezinye izinhlobo ezintathu zabadlali bendabuko.
Abacwaningi babeka ukuthi isizathu esisodwa sesikhathi esifushane sokuphila kwabadlali be-kabuki kungaba ukuthi ukuqeqeshwa ukumelana ngokweqile futhi ukuvivinya umzimba kuqeda izici ezizuzisayo zokuvivinya umzimba njalo. Esinye isizathu kungaba ukuthi esikhathini esidlule, abadlali be-kabuki babevame ukusetshenziswa oshiroi (impushana emhlophe esetshenziselwa ukwakheka) equkethe umthofu, oyingozi enkulu empilweni. Ukusetshenziswa kwe-oshiroi kwavinjelwa kuphela eJapane ngo-1934.
Abacwaningi baqaphela ukuthi ucwaningo lwabo alunayo imingcele. Isibonelo, idatha ibheke kuphela ubungcweti obusa amadoda ngakho-ke ayinikezi umbono wobude besikhathi sonke sabantu, okuhlanganisa nabesifazane. Kuzodingeka umsebenzi owengeziwe ukuze kuhlolwe inani eliphelele lokuzivocavoca ukuze kuvikelwe impilo. Imiphumela engaba yinzuzo yemisebenzi 'engawuvivinyi' efana nokukhuluma, ukucula nokudlala izinsimbi zomculo nayo izodinga ukuhlolwa okwengeziwe.
Sekukonke, abacwaningi bathi ucwaningo lwabo lumele "indlela entsha yokukhipha imininingwane kudatha etholakala esidlangalaleni»Futhi«inomthelela enkambweni yomhlaba wonke yokubhekana nokuphindaphindeka kwesayensi".
